Sohaib Mohamed 6f2021f3d9 PCP: support for 'dynamic columns' added at runtime
Implements support for arbitrary Performance Co-Pilot
metrics with per-process instance domains to form new
htop columns.  The column-to-metric mappings are setup
using configuration files which will be documented via
man pages as part of a follow-up commit.

We provide an initial set of column configurations so
as to provide new capabilities to pcp-htop: including
configs for containers, open fd counts, scheduler run
queue time, tcp/udp bytes/calls sent/recv, delay acct,
virtual machine guests, detailed virtual memory, swap.

Note there is a change to the configuration file path
resolution algorithm introduced for 'dynamic meters'.
First, look in any custom PCP_HTOP_DIR location.  Then
iterate, in priority order, users home directory, then
local sysadmins files in /etc/pcp/htop, then readonly
configuration files below /usr/share/pcp/htop.  This
final location becomes the preferred place for our own
shipped meter and column files.

The Settings file (htoprc) writing code is updated to
not using the numeric identifier for dynamic columns.
The same strategy used for dynamic meters is used here
where we write Dynamic(name) so the name can be setup
once more at start.  Regular (static) columns writing
to htoprc - i.e. numerically indexed - is unchanged.

Bart Bakker c1c4b5a1ab
Read settings after applying defaults
Default settings are used as a base and only settings specified in `htoprc` are
applied on top of it. This patch removes the special case for applying some
defaults  when the config does not contain a `meters` key. All defauls are set
before any attempt to read settings, so only keys actually present in the config
file are overridden.

Hisham Muhammad 2327260ee8 Separate tree and list sort orders
Implements the suggestion from https://github.com/htop-dev/htop/issues/399#issuecomment-747861013

Thanks to the refactors from 0bd5c8fb5da and 6393baa74e5, this was really easy
and clean to do.

It maintains the "Tree view always by PID" option in the Settings, which
results in some specific behaviors such as "clicking on the column header to
exit tree view" and "picking a new sort order to exit tree view", for the sake
of the muscle memory of long time htop users. :)

Zev Weiss 2899ed4cb0 Number CPUs from zero by default.
Numbering from one is idiosyncratic and inconsistent with basically
everything else in the world; it doesn't make much sense as default
behavior.

All naming is updated to reflect that numbering from one is a
non-default, opt-in option.  The old label of the flag saved in htoprc
("cpu_count_from_zero") is still supported for backwards compatibility
with existing configs, however.

Nathan Scott c9ecd0fa74 Revert the vim_mode setting for now, needs a rethink
There have been too many bugs reported in vim_mode, and
the proposed fixes are increasingly fragile - hence we
have decided to back it out for now.  For reference:

   https://github.com/htop-dev/htop/issues/69
   https://github.com/htop-dev/htop/pull/37
   https://github.com/htop-dev/htop/pull/106

The whitespace changes also arrived in commit 12805f61d
not sure what that was about, but backed out as well.
